.To all whom it may Concern .f

Be it known that l, THOMAS GRAY, a citizen ofthe Dominion of Canada, residing at Buffalo, county of Erie7 and State of New York, have invented certain new and useful improvements in Charging-Trucks, of-

' ...jy-have provided a charging truck which is cheap to manufacture and cheap and convenient to operate. With my truck there is no steam boiler to obstruct the view of the operator, and/no escaping steam to bother orinconvenience him when the charge is run L.into the furnace and-let down. Furthermore, my truck, in itsgpreferred construction, carries its own 'source of power and is complete. independent power unit and therefore does not require a hose or like-conductor to-.connect it with vthe source' of power. Obviously, if desired, l may dis- @run a flexible electric conductor from niy Ltruck' to any stationary and conveniently 'f1 arranged .source of electric power. Moreover,fmy .truck is already for servicel at a niinutes. notice u'fithout having to get up "Leain o r compressed air and when not in use hether for a short or long time, all expense eases.v

'Referenceisfto be had to the accompany- .ing drawings, .forming part of this specifil ycation,.in 'which like characters of reference indicate like parts throughout the several iews of which: e Figure 1`is a side view of my truck with "ff'afportion ofone of the wheels broken away. 2 i's va plan view ofmy invention with a portion thereof broken away. F'gz 3 is a i. Afront viewof my truck showinga portion 5G' thereof'in section. Fig. il is a sectional viewK Fig. 6 is a perspective viewiofithe'clutch operating wedge used in my device. l

Referring now to the drawings, 1U represents the frame of my truck which is prefer- Vably made in two parts. These two parts .are secured together by any of the well known means. two driving wheels 13 and 14C and one steering wheel 15. I

1i is a. bracket .which is secured to the rear end of the frame 10 and overhangs the.

steering wheel 15. The Vsaid steering wheel' is rotatably carried by a fork 16, at the rear end of the frame. Secured to the top of the fork and rotatably and slidably carried by the bracket-17 isa stem l1S. This stem eX- Ths frame is carried 'by'l ltends up through the bearingion the bracket i 17 and .has securedto its upper end a flange 19 provided with a ball race. A disk 2O pro vided nath a similar ball race is disposed said disk is a series of' balls. some distance above said diskis a thrust disk 21 which is held in place bymeans of the bolts 21?. A helical spring "22 is disposed between said thrust diskl and the disk.

above the said flange 19 and between it and y Carried at 20, thus serving to keep thestein 18 non i said pinion is secured to a shaft 2:5y which islv suitably carried by the bracket ,17... The( shaft 25 is provided at its upper end with a crank 26 by which the pinioncarried by said" shaft may be revolved and thusy steer the truck. A seat 11 is suitably vsupported on. a spring 12 which is (secured, to the'- bracket 17. i l, n

The driving wheels 13 and 1d vare rotatably disposed upon a stationary. shaft 27. `This shafthas rigidly mounted thereon, blocks 28 and 29 and to these blocks are secured the front ends of thefraine 10. vThe wheels 13 and 14 each have va recess in the outer face of the hub and inthisyrecess is taken on line A-B of F ig. 2. Fig. `5 is disposed a flange 30 whicliissecured to theV sectional view taken Online C-Dof Fig.

- endfof the stationary shaft 27,1 thus keeping between the4 same.

the said wheels in pla-ce on said shaft. In the front and back face of each of the blocks 28 and 29 is provided a groove as .shown and slidably disposed in these grooves are slides 31. These slides are longer than the blocks 28 and 29 and a plate 32 secures the bottom ends thereof together. Disposed at the top ends of the said slides is a yoke 33 which is suitably bolted to the said ends. A spring 33n is disposed between the yoke 33 and each-of the blocks .28 and 29 and normally hold the slides 31 in their uppermost position. At each end of the yoke 33 is a downwardly extending L-shaped arm 34, each carrying at its lower end a roller 35. Above the lower leg of each of the L-shaped arms 34 is disposed the outer end of a roller arm 36; `Each of said roller arms carries a roller 37. The rear end of each of the said roller arms is pivotally carried by a support 38, one of said supports being secured to each side of the frame 10 as shown.

A lifting frame or fork 39 is carried by the frame 10 'and is pivoted at its rear end to said frame at preferably some point near the rear of the truck. This fork extends forwardly for some distance beyond the d riving wheels 13 and 14 and is supported Extending across the front end of said fork is'a vertical back or support 40 which is properly secured to the said fork and which prevents the annealing pots from tipping over when the' truck is moved about. To each side of the lifting frame' or fork,39 is pivotally attached the lower end of'one'of ythe fork supporters 41. These fork supporters extend upwardly and are so formed that they pass around the central hub o'f. the driving wheel and other mechanism located on the vertical centerline. At the upper end of each of the said' fork supporters is provided an elongated aperture or slot 42 in each of which is slidably disposed one of the bearing pins'43. The said bearingl pins are made preferably integral with the yoke 33 and serve to keep the fork supporters in` their proper position as they are moved up and down. 'The upper end or lhead of each of these fork supporters is greater in width than the lower portion and directly beneath jthe said head on each of said fork supporter-sis disposed the outer end of one of the' roller arms 36. The said roller arms are each provided with a head, thus providing a suitable hearing for each of said fork supporters. Between the roller 35 of each of the L-shaped arms-34 and the roller 37 of each of the roller arms 36 is disposed 'a lifting wedge 44 for increasing the distancebetw'een said rollers. The rear end of each of the said wedges is carried between suitable rollers 45 carried by the support 38 and when thevlifting frame or fork is to.be operated these wedges are moved longitudinally by means hereinafter drawn back, thus\`\temporarily locking the said wedges'when the lifting frame is carrying a load.

As hereinbefore statedluse electricitywas the .source of motive power 'for my truck and in the drawings I have represented, in a diagrammatical manner, an e ectric storage battery-46 and an electric motor 47..

48 is the electric controller and\49 the operating lever of the same.

Suitable electric connections (not shown) are made-between the battery motor and controller. The said battery motor and controller are suitably secured to and carried by the frame 10. One end of the shaft 50 of the motor 47 extends out beyond the side of 8'5 the frame as shown (Fig. 2) and has a spur gearY pinion 51 Asecured thereon. Meshing with the pinion is a spur gear 52 which is mounted rigidly upon the outer end of a hollow shaft or sleeve 53. Rotatably disposed within the said sleeve is a shaft 54. This shaft and sleeve are rotatably carried by the frame 10 in suitable bearings as shown. Connecting the sleeve 53 with'the shaft 54 is a wedge operating clutch 55. 95 The female member 56 of the clutch vis `rigidly mounted on the inner 4end of the said l 59.' The rear ends of the connecting rods 110 63 and -64 are rotatably connected to the crank shafts 61 and 62, respectively. The front ends of said connecting rods are each connected to one of the lifting wedges 44. Thus by revolving the crank-shaft 60 the 115 ,said .wedges are operated to either raise or .lowerl the liftmg frame or vfork 39. vl: have found that 1t 1s necessary when operating the said wedges to provide some means for automatically throwing thewedge operat- 120 ing clutchout of engagement at predetermined4 positions and thus 'stopping the revolution of thecrank-shaft 60. `I accomplish this bythe mechanism which I will now describe. j y

Carried by the frame 10 (Figs. 2 and 5) isa 'supporting member 104 which straddles the shaft 54 and carries at its upper end a roller 105. 'Bearing against the ,roller `i105 land slidably disposed'in the said supporting 130 member. i

message member is an operating wedge 65. Bearing against the opposite sideof the wedge 05 is a roller'66 which is carried by a roller arm -67. This rol-ler arm is pivotally carried by the arms 68 of the supporting member 104. The said supporting member is provided with arms 69 between which is pivotally mounted a yclutch operating lever 70. rfhe upper end of this lever is in contact ,with the outer end of the roller arm 67 and the lower end of saigllever is forked and in engagement Awithandannular groove 71 provided in the male Aclutch member 57. Rotatably mounted on the shaft 54 and disposed beneath the wedge 65 is a clutch operating gear 72. This gear meshes with a spur gear 80 of the same diameter, which is rigidly mounted upon the crank-shaft 60. The gear 7 'fs .provided with two fingers 7 3 which are set dia-metrically opposite each other and arranged to pass through a slot 74 provided in the supporting member 104 when thel said gear is revolved. ."Vhen the said gear is revolving7 the clutch 55 is of course7 in engagement and the wedge is then in the position shown. T he wedge is provided on its under side with a notch 75 (Fig. 6) and when either of the fingers 73 passes through the slot 74 they engage with thesaid notch and'move the wedge so as to' disengage the clutch A helical spring 76 is disposed around the sha t 54 and between the gear 72 and the male member 57 vof the clutch. This spring serves to press the clutch members into engagement when thev wedge is pushed forward. The vwedge 65 is provided with a bifurcated end 77 whichv has pivotally connected thereto an operating lever 7 8. The operating lever is provided at therear end thereof with a suitable handle 79 which is conveniently located for the operator`:`.`-

The propelling' mechanism of my truck is as follows: The inner face ofeach ofthe driving wheels 13 and 14 is provided with o spur gear teeth and meshing` with these teeth of each of said wheels is a driving 4pinion 106. Each of said pinions is mounted on one end of the differential shaft S1 which is suitably carried in bearings by the frame 10. Mounted onthe said differential shaft and located near the center of the frame10 is the differential gearing 82. This differ'- ential gearing isof the usual type and need not here be` described in detail. Meshing with the said differential gearing is a pinion f 88 which is rigidly mounted upon a tubular shaft 84 .(Fig. 4). )Vithin this tubular shaft is rotatably mounted Aa shaft 85. The said tubular shaft S4 and shaft S5. are rotatably carried by the frame 10 in suitable bearings "as shown. A driving clutch 86 is provided by -which the said shaft 85 is engageable with the tubular shaft 84. The female mem.- ber 87 of the said clutch is rigidly secured inner end of to the tubular shaft'84 and the male member 88 thereof is slidably disposed on the shaft 85. ln the bearing 89 (Fig. 4) is disposed,

in a fixed position, a sleevef90.r This sleeve is flanged at both ends as shown, and este 70 tends inwardly toward the clutch S'f A roller flange 91 is rigidly7 mounted-,on the' said sleeve.. This 4roller: iiafnge is provided with two rollers 922 disposed` i preferably diametrically oppositegeach othevi'g` 75" and they extend from the face of said flange which is toward the bearing '.nopverat-f ing flange 93 is rotatablyjdisposed upon the sleeve and has one Iof its facesv bearingv against. the rollers 92. ln the faceof the a operating angs which bears against the rollers 92 aie*previdednotch'es 94 which are engageable with theA said rollers when the operating flange is revolved.. Connecting y the male members 8S of the operating clutch S5 with the operating flange 93 is a transverse ycke-95 (Figs. 2 and 4). The said clutch member and said 'flange are each provided with an annular groove and the said yoke is rotatably engaged with said groove. ,A 90 lever J6 is rigidly connected with said ope erating flange and extends upwardly, hav-k ing pivotally connected at itsupperend ant operating link 97. A suitable handler9$ provided on the inner end of said operating 95 link which is conveniently located for the operator. Standards 99 are secured tothe frame of the truck and in these supports the respective operating lever 7S nand link i 97 are slidabl; disposed. Av stop 100`is pref; le@ erably provided on the operating link 97 to limit the movement thereof. 'A helicalV spring 101 is arranged around the sleeve 90 -and bears against the bearing89 and theoperatingfiangie. The shaft 85 isdri'ven 'by 105 means of a spurgear 103 which Y,is rigidly 4 secured to the outer end thereof'and which meshes with the spur gear 52. 'i y Having thus described my invention, I i will now describe its operation.' K y '110 W'hen git is desired to 'propel my truck. ythe motor 47 is set in motion. The power de- `rived therefrom is carried `to the shaft S5 Vby the gears'hereinbefore described."` The( operator now pushes, the operating link`97 "115 forward. This, through' the-medium of' t'lie lever 96, revolves the operating flange 93 thus permitting'the notches`9-tv 'to engage with the rollers The'said operating flange and the male memberBS of lthe opei'- "1129i ating clutch are nowgiven a 'longiti'xdinal movement bythe spring 101 andthus throw the said clutch into engagement.. To `reverse the direction of travel of the truck, the direction of rotation versed. i v s rl`he wedge operating clutch for convenience in the drawing' is sh'o'wn 'in engagement but obviously the clutch is normally out of engagement. To engage -thisclutch 13a ofthe motor is reand set the parts as shown, it is only necessary for the operator to push the operating lever 'I8 forward. Then the clutch parts are in the positions shown the crankshaft 60 will be rotated, but as the shaft revolves the gear 8O mounted thereon also revolves. This gear S0, as hereinbefre stated, meshes with the clutch operating gear 7 2 and when the clutch operating gear is revolved'one of the lingers 73carried thereby engages with the notch 75 provided on the wedge 65 and pushes the said wedge rearwardly. When the'said wedge is'moved as-just described the roller arm 67 is given aswinging movement which,v through the medium of the clutch operating lever 70, throws the clutch 55 out of engagement. When the said crank-shaft 60 is rotated from the position shown, the wedges All are drawn backwardly until the indentation 102 in the summit of each is'directly beneath one of the rollers 37 carried by the roller arms 36, at which time the clutch `55 is automatically disengaged. y It w'ill be understood, that the release 4of the clutch 55 is so timed that it is disengaged shortly before the lifting wedges 44 and the rotating parts of the device have come to rest, when the lifting wedges are operated in either direction. Thus, after the clutch is disengaged, there is sufficient momentum of the rotating parts to carry either of the fingers 73 far enough, so as to be out of engagement with the notch 75, whereupon the wedge may be again operated' to throw .the clutch into engagement when desired. lhen the wedges are in the position just described the lifting frame or fork 39 is in its raised position. When it is desired to lower the said fork the crankshaft GO is again revolved which pushes the said wedges 44 forwardly. The said crankshaft is stopped automatically when the said wedges reach the limit of their forward movement or when the said fork is in its lowermost position.

It should be understood that instead of the electric power means herein specifically described, other suitable-power means such as an internal combustion engine may bev employed in my truck and substantially the same advantages may thus be attainedu as those herein set forth. Clearly too, a cam or eccentric could be advantageously used in my device in place of the specific wedge construction shown and described. Other -detailed 1nodifications of the device herein shown and described may be madewithout departing from the spirit of my invention and I do not wish to be limited to the exact embodiment herein shown and described.

Having thus described my invention, what I claim is: i
